A group of researchers in Thailand outlined a new methodology to identify the optimal temperature in two-stage cascade heat pumps using non-azeotropic refrigerants. Through their analysis, the ...

An international research team has conducted the first empirical study on retrofitting PV-assisted two-stage heat pump (HP) systems in existing multi-family buildings. The research is part of the ...

Conventional district heating systems are generally designed around the load. However, an alternate approach would be to design around potential heat sources, including the waste heat from power ...
